Olivia Wilde was my Best Dressed of all those who attended the Oscar after parties.

The stunning actress wore a buttery yellow RM by Roland Mouret “Hydra” gown.

The organza ruffle front gown was a beautiful colour on her, which she paired with a maroon clutch and matching Ferragamo satin heels.

Bold red lips and loose waves completed the look.

Roland Mouret also dressed Anna Paquin for the 2010 Vanity Fair Party.

Anna has been taking a lot of risks lately wearing Viktor & Rolf, Alexander McQueen and Marios Schwab, so her black RM by Roland Mouret “Latona” dress feels a bit tame in comparison to her riskier ensembles.

She would’ve totally rocked the orange version and I’m really surprised that on her current form she didn’t go for it.

The actress paired her dress with a Maia N python box clutch and a House of Lavande vintage seven strand gold ball necklace.

Selma Blair wore a very formal look to the 2010 Vanity Fair Party on Sunday night.

When I saw Selma wearing this ensemble I instantly thought of Nicole Kidman.

This is because I can so picture Nicole wearing this look to a press conference or a daytime event.

It’s definitely not a party look.

The young actress wore a midnight blue riding jacket, paired with a black taffeta ruffle shirt and black beaded high-waisted skirt from L’Wren Scott’s Fall 2010 collection.

Apart from this look not being Selma’s style, she looks very restricted and uncomfortable.

This was made for someone of Nicole’s height for sure, because it’s not a bad look. Just bad on Selma.

Selma wore her ensemble with a pair of Christian Louboutin new Helmut black nappa leather pointy-toe pumps.

Valentino was the designer of the night at the 2010 Vanity Fair Party in LA.

My favourite was Kate Bosworth who was a stunning vision in red.

The ruffles on her one-shoulder Valentino Pre-Fall 2010 gown were slightly flat, but I think stops her from being overwhelmed in this big gown.

Her hair was swept to the side whilst she opted for a pink lip colour to complete this stunning look

It looks like the parties are as well dressed as the main event.

Amanda Seyfried changed out of her Armani Prive gown, to this edgy Valentino Spring 2010 Couture look for the 2010 Vanity Fair party.

Her green couture dress appears to be made out of strips of leather which she matches with green earrings.

I’m not sure if it’s the light, but I prefer the darker runway version of this look.

Her look was complete with a silver metal Ferragamo clutch with rhinestone details and a pair of bronze sequin Ferragamo booties with metal heel.

I love how Amanda went from princess to diva from one event to the next.

Jessica Seinfeld arrived wearing a Valentino Resort 2010 beige knit dress.

The dress was trimmed with feathers both on the neckline and hem.

Nice dress, but I preferred the strappy runway heels.

During her Fall 2010 presentation, Victoria Beckham announced to her invited guests that she was going to wear the above gown to Elton John’s Oscar party – which she did.

The problem with her announcing which look she was going to wear was that it took away the anticipation and excitement out of her look.

She does look great in her self designed dress. I love that it’s not black – like she wore last year – as her face feels brighter, but this could be due to the lighter make-up and lighting.

She was easily one of the best dressed at the Oscar parties.

Cameron Diaz’ look I didn’t see coming.

At the Vanity Fair Party the blonde actress arrived wearing my favourite look from Victoria Beckham’s Fall 2010 collection.

The gold/silver shimmering asymmetrical dress is stunning, but the thud at her feet is still ringing in my ears.

I love you Rachel. You’re an amazing stylist, but what’s with these black pumps paired with nearly everything for your clients?

Demi Moore doesn’t hit a red carpet without black pumps either.

With the amount of shoes Rachel has on offer this really lets me down.

Young Emma Roberts was one of the many guests to arrive at the 2010 Vanity Fair Party in LA Sunday night.

I loved her Reem Acra Resort 2010 dress with a tulle bust detail…on the runway.

I’m not sure why it was modified to look so provocative.

Yes she’s 19, but the split on the bust doesn’t work for me, but I do like the shorten length.

Her look was paired with Martin Katz jewels.

Gustavo Cadile dressed two stars on Sunday night for the Oscars and Oscar parties.

E! TV presenter Giuliana Rancic wore a navy and black ball gown from the designers Fall 2010 collection.

The strapless mermaid-silhouette gown was paired with matching crystal embellished clutch to complete this stunning look.

Carla Gugino attended the 2010 Vanity Fair Oscar Party also wearing a dress by the same designer.

Carla opted to go short wearing a strapless navy and black taffeta party Fall 2010 dress.

She paired her dress with a Jimmy Choo ‘Emerald’ heels.

Kathryn Bigelow made history at the 2010 Oscars by becoming the first woman to win the “Best Director” Oscar for ‘Hurt Locker’.

She was also a winner on the red carpet wearing a Yves Saint Laurent Edition Soir gown by Stefano Pilati.

The stunning feature of this titanium silk satin gown was the beautiful embroidered bodice.

To complete her look Kathyrn paired T-strap YSL silver sandals with a YSL titanium satin clutch.

Boucheron jewels completed the look, but the red bracelet was a tad distracting.
